capon: [OE] Capon, a ‘castrated male chicken’, is probably literally a ‘cut cockerel’. The word comes via Anglo-Norman capun from Latin capō, which is probably ultimately derived from a word for ‘cut’ – Greek kóptein, for example – the underlying reference of course being to the cutting off of the unfortunate bird’s testicles.
